ELECTRICAL TIME CUT-OUT FOR CONTROLLING RAILWAY-BARRIERS OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 772,368, dated October 18, 1904.

Application filed May 26, 1904. Serial No- 209,893. (No model.)

To all whom, it may concern:

Be it known that I, FRANZ. NEUGEBAUER, a subject of the German Emperor, residing at Goldschmieden, near Deutsch Lissa, Silesia, Germany, have invented certain new and usefullmprovements in or Connected with Electrical Time Gut-Outs for Controlling Railway- Barriers or the Like; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to'which it appertains to make and use the same.

This invention relates to one of the ordinary quicksilver time cut-outs in which the working circuit is closed by means of a twochambered tilting. vessel filled with quicksilver, the time occupied by the quicksilver in passing from one chamber to another determining the time during which the working circuit remains closed, a local circuit being closed after the quicksilver has run down,

whereby the tilting vessel is returned to its original or normal position by a motor or solenoid. At the same moment accordingly the working circuit is broken. If such time cut-outs be employed in railway working for the ringing mechanism connected with the barriers or for moving the barriers, the tilting vessel being released by a rail-switch the signal sounds on the barrier and the barrier is lowered as soon as the time cut-out is released by closing the rail-contact, the cut-out remaining in the released position until the quicksilver has run down and effected the closing of the local circuit, whereupon the cutout is immediately returned to its original position by a solenoid or'electromotor and the working circuit for the signaling mechanism and the barrier interrupted. The barrier is accordingly raised again and the signaling mechanism ceases ringing. If the train which pressed down the rail-switch stops between the switch and the barrier, the barrier may have already opened again and the ringing mechanism be silenced. When the train went on again, it would pass the open and unsecured barrier. The present invention is intended to obviate this difliculty.

Figure l of the drawings is a diagrammatic view of a switch arrangement with one of the ordinary time cut-outs. Fig. 2 is a section through A B of the time cut-out; Fig. 3, a side elevation of the same. Figs. 4: and 5 represent different positions of the new switch device used for the usual time cut-out.

The tilting vessel, which consists of the chambers a and b, is'pivotally suspended at c and retained by the armature d in the position indicated by dotted lines. The armature when attracted by the electromagnet 6 releases the tilting vessel, which then swings down, Figs. 1 and 3, and the quicksilver runs slowly out of the chamber a into the chamber 6. Contact-pins f g are run into the chamber I). When the vessel is tilted down, these pins bear against conductor-springs h z. The local circuit k 70, in which the motor Z is inserted, is connected with these springs. When the quicksilver has risen in the vessel 5 as far as the contact-pin c', the circuit 76 is closed, the motor Z acts and turns the tilting vessel back into the position indicated by dotted lines in Fig. 3. When the vessel Z) is in its lowered position, a spring m is pressed down thereby onto a contact-pin n, and the working circuit 0 0 closed. This circuit remains closed until the quicksilver closes the circuit 70. At this moment, howeverthat is, when the tilting vessel begins to move upward, owing to the action of the motorthe spring m is released and the working circuit interrupted.

According to the present invention railswitches q r are arranged; respectively, in front of and behind the barrier 19. Each of the rail-switches is connected with two circuits s t and t a, the circuit 8 t being closedout has run down. An electromagnet sis inserted in the circuit t u and actuates the contact-lever m.

The action of the apparatus is as follows: When a train runs over one of the railswitches 41 or r in the direction of the barrier p, it reverses the particular rail-switch, and thus closes the circuit .9 t. The electromagnet c is energized and the time cut-out put in circuit, which actuates the safety apparatus, but at the same time the armature w, being attracted by the electromagnet o, releases the contact-lever 00, so that the lever 02 swings downward and interrupts the circuit is at If the train now remains stationary between the rail-switches q so that the time cut-out,

has run down and closed the circuit is by means of which the safety device is returned to its starting position before the train has passed the barrier, the barrier cannot return to its original position because the circuit in is interrupted at Thus the safety devices continue to act until the train has moved in one or the other direction and again passed one of the rail-switches q '2'. This is illus trated in Fig. 5. The rail-switch r afterthe train has passed it has been returned to its starting position, so that the electromagneto has been without current and released the armature w. At the moment when the train passes the contact q it closes the circuit t u. Hereby the electromagnet 2 is energized and attracts the contact-lever m. Thereby the circuit 7c is closed at so that the safety devices can return to their original position. The armature w falls again, engages the contact-lever in, and holds the lever in the circuitclosing position.

What I claim, and desire to secure by Letters Patent, is

In a time cut-out of the kind referred to for controlling railway-barriers, in which the cut-out is returned to its normal position by the closing of a local circuit, a current-interrupter arranged in the local circuit, electromagnets controlling the said interrupter, separate electric circuits adapted to energize the magnets, and rail-switches arranged in the magnet-circuits and placed in front of and behind the barrier, one of the switches being adapted to be operated by a train before arriving at the barrier to complete the circuit of one magnet and thus break the local circuit and the other switch being adapted to complete the circuit of the other magnet and thereby the local circuit, substantially as described.

In testimony whereof I have aflixed my signature in presence of two witnesses.

FRANZ NEUGEBAUER.
